CARDS SHUFFLING / RANDOM NUMBER GENERATOR

Technical Systems Testing RNG

TST laboratories provide fully independent and impartial testing and certifications for industry operators, suppliers, manufactures and regulators. TST analyzes system software and equipment, and the environments in which they operate, against manufacturer's specifications, legislative and regulatory requirements, and to generally accepted industry standards.

Microsoft CryptoAPI RNG

The Greek Poker uses the cryptographically-secure RNG system found in Microsoft's CryptoAPI. "Cryptographically secure" means that the RNG is so completely random that even a large amount of computer analysis cannot predict or detect patterns in the output, a fact that has been validated by the National Institute of Standards and Technology (NIST).

Microsoft's CryptoAPI RNG complies with Federal Information Processing Standard 186-2 appendix 3.1, using SHA-1 as the G function. It has been validated by the NIST's Cryptographic Module Validation Program.

It is important to note that computers are deterministic machines, and as such, they cannot produce truly random numbers. For this reason one often refers to Pseudo Random Number Generators (PRNG). Pseudo implies that a PRNG does not produce truly random numbers, but numbers that are random enough for a specific practical use.

The validation of Microsoft's CryptoAPI by the National Institute of Standards and Technology proves the PRNG system used is highly random and highly secure as it is a critical building block for the CryptoAPI. For more information on NIST processing standards and security validation, please visit:
